A small-lift launch vehicle is a rocket orbital launch vehicle that is capable of lifting 2,000 kg (4,400 lb) or less or under 5,000 kilograms (11,000 lb) of payload into low Earth orbit (LEO). The next larger category consists of medium-lift launch vehicles.

A launch vehicle is typically a rocket-powered vehicle designed to carry a payload from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs.
